Infinity Full Range Class D Amp

This amp is QUALITY! I bought one of these last time around to upgrade my car audio (along with a Kappa 12" sub and Kappaone amp for it). I have never heard a 4-channel amp deliver as clear of sound as this. I have heard other big name amps throughout the years (RF, NVX, etcetc), but I can easily say that this is in a league of its own. For this price, you should pick up three.
